Getting `System.IO.FileNotFoundException` for .pdb

[64J0]

Description:

Hello, hope you're good. I'm opening this issue to ask for guidance on how to deal with this error:

# the command I used:
dotnet minicover instrument --workdir ./ --sources "source/**/*.fs" --exclude-sources "source/Tests/*.fs" --tests "source/Tests/*.fs"

#...
# logs checking assembly files, and assembly instrumented in the end
# ...
Unhandled exception. System.IO.FileNotFoundException: Could not find file '/tmp/minicover/fff1ada6-53fe-4c90-866c-b19e821421b3.pdb'.

And when I check what is inside the /tmp/minicover/ folder, I get:

ls /tmp/minicover/

abe3cbba-b9af-4155-a154-3679166f6d9f.dll  
fff1ada6-53fe-4c90-866c-b19e821421b3.dll

So, no .pdb was generated.

Also, I'm using minicover version 3.6.1.

It worked after removing the --exclude-sources "source/Tests/*.fs"
